Objectives:To understand the human resources and costs of essential public health services based on community health service centers in Beijing’s rural areas and to offer policy recommendations for advancing the progress of essential public health services. Methods:With the self-designed questionnaire, the paper collected data from the districts of Changping, Tongzhou, Huairou and Miyun. By cluster random sampling, 12 community health service centers and 108 personnel were surveyed based on the level of economic development. Results: The number of young women, preventive personnel and staff with low ranking positions represents a significant share of all essen-tial public health service providers. Beijing’s rural areas deploy a great deal of human resources for vaccination and health education with little set aside for women’s health and reproductive health. The unit cost of setting special col-umns for health education and field disease treatment is higher than other service items. The suburbs deploy a great deal of human resources for service items than the outskirts while the unit costs are lower. Conclusions: Human re-source for essential public health services in Beijing’s rural areas should be strengthened. The costs of service items differ greatly so that policy adjustments and finances should be implemented based on actual demand and resources.

Objective:To develop a simple and efficient method for constructing a middle fragment-deleted mutant of MHC class Ⅱ molecule transactivator(CⅡTA)mutant with the 109~(th)to 226~(th) amino acid codons deleted.Methods: Two gene fragments at each end of the deleted CⅡTA gene were obtained by OE-PCR method and were mixed together for 8 PCR cycles without primers to achieve effective overlapping,then 2 primers was added for amplification of the desired fragments.The amplification products were subsequently cloned into eukaryotic vector pIRES for identification.Results: A mutant of CⅡTA with the 109~(th)to 226~(th) amino acids deleted was successfully constructed.Conclusion: This modified OE-PCR technique overcomes some shortcomings of traditional method and is very suitable for constructing mutants with middle fragment deletion,making it worth to be popularized.

Objective To investigate the leptin in continuous ambulatory peritoneal dialysis(CAPD)and its influen- cing factors.Methods 30 CAPD patients and 30 henhhy controls were enrolled in the study.Leptin was measured by ELISA.C reactive protein(CRP)by transmisson turbidmetry.Body mass index(BMI),fasting insulin(FINS), blood urea nitrogen(BUN),serum creatinine(Scr)etc were also determined.These patients were classified to two nutritional categories based on SGA normal nutrition and malnutrition.The relationship between serum leptin concentra- tion and these indices was analysed.Results Serum leptin levels in CAPD group was significantly higher than those of healthy control(P

A comparison was made for the correlation and application scope of the statistical methods commonly used by hospitals for their efficiency measurement.Hospital data processed with PCA (principal component analysis)for dimension reduction were used in a correlation analysis for the results of ratio analysis (RA),stochastic frontier analysis(SFA)and data envelopment analysis(DEA).The authors hold that the RA can expediently display the order of hospital efficiency,the SFA demands a stricter premise yet presents more stable results,while the DEA boasts greater relative advantages and thus suitable for processing hospital efficiency measurement tasks of multi-input and multi-output indexes.

Objective To investigate the clinical efficacy of herbal cake moxibustion in treating chronic renal failure. Methods Sixty CRF patients were randomly allocated to treatment and control groups, 30 cases each. The control group received medication and diet control and the treatment group, herbal cake moxibustion on Shenshu, Pishu or Ganshu in addition. Pre-/post-treatment differences in serum creatinine (Scr), blood urea nitrogen (BUN), endogenous creatinine clearance rate (Ccr) and 24-h urinary protein quantity were observed in the two groups and the clinical therapeutic effects were compared between the two groups after 3 months of treatment.Results The marked efficacy rate and the total efficacy rate were 46.7% and 86.7%, respectively, in the treatment group and 20.0% and 46.6%, respectively, in the control group, and there were statistically significant differences in both between the two groups (P<0.05). There were statistically significant pre-/post-treatment differences in Scr, BUN, Ccr and 24-h urinary protein quantity in the two groups (P<0.05). There were statistically significant post-treatment differences in Scr, BUN and 24-h urinary protein quantity between the treatment and control groups (P<0.05).Conclusion Herbal cake moxibustion is an effective way to treat chronic renal failure.

Objective To measure the length and diameter of the main bronchus using three-dimensional reconstruction from spi-ral chest computerized tomography scans in Chinese patients,and to evaluate the relationship between the BMI of patients and the length and diameter of main bronchi in order to provide the basis for pre-operative tracheal intubation.Methods 100 males and 100 females,who were scheduled to undergo a chest CT scan for physical examination,the diameter at the carina of the left and right main bronchus were measured.The length of the main bronchi extending from the carina to the line that is vertical to the bronchial wall at the starting point from the branches of the upper lobe was measured at the workstation.Results the length of the men’s right and left main bronchus was (1 9.7±5.2)mm and (50.3 ±4.7)mm.the length of the women’s right and left main bronchus was (18.2±4.1)mm and (46.3±4.5)mm,The length of the left main bronchus(LMB)was about 3-4 times greater than right main bronchus(RMB).the cross-section of the men’s left and right main bronchus was (175.3±29.6)mm2 and (209.4±32.7)mm2 ,the cross-section of the women’s left and right main bronchus was (120.5±24.8)mm2 and (144.4±33.7)mm2 .There was no signifi-cant relationship between the length and diameter of main bronchi and the BMI of patients.Conclusion The results showed that there was no direct relationship between the diameter and the length of main bronchi and the BMI of patients.BMI is not the criteri-on for choosing double-lumen tube (DLT)size.We proposed that three-dimensional reconstruction be used to measure the size of the main bronchi and determine the optimal size of the DLT in a clinical setting.

To discuss the value of the diagnosis and treatment for the submucous myomas by hysteroscope. According to the data of hysteroscopic resection in the treatment of submucous fibroids, the authors suggested that the submucous myomas should be divided into four types and the detailed appearance of each type were discussed. Conclusions: Four types of the submucous myomas were distinguished and the surgical treatment of each type were chosen correspondingly under hysteroscope.

To analyze the pathogenesis, clinical symptoms, misdiagnosis and operation of endometriosis in unusual sites,32 cases of unusual site endometriosis were analyzed. 468% was correctly diagnosed before operation,and 625% was found to have a history of operation.Good prognosis can be achieved by combined treated on the basis of discussing its pathogenesis clarifying its increasing incidence rate,and attaching importance to its malignant tendency.
